Dietary nitrate consumption improves arterial function in hypertensive patients. The effects of 4 weeks dietary nitrate consumption (beetroot juice 250 mL daily) or placebo (nitrate-depleted beetroot juice 250 mL daily) on clinic measures of (A) PWV, (B) AIx and (C) % and (D) absolute increase in vessel diameter with FMD. Data are expressed as mean±SD. Significance shown for comparisons between treatment allocations of the change between Pre and Post for unpaired Student t test; and as ++p<0.01 and +++p<0.001 for Dunnett’s post hoc test comparison to baseline (Pre) following 2 way ANOVA for changes within each treatment allocation cohort. (AIx=augmentation index; FMD=flow mediated dilatation; PWV=pulse wave velocity; Pre=1st visit pre-intervention; Post=2nd visit post-intervention; W/o=3rd visit washout).
